SWITCH-RAIL CHAIR.

SPECIFICATION forming part; of Letters Patent No. 394,309, dated December 11, 1888.

Application filed August 2, 1888. Serial No. 281,787 (No model.)

To all whom it nmg concern:

Be it known that I, AXEL A. STROM, a citizen of the United States, residing at Austin, in the county of ook and State of Illinois, have invented a new and useful Improvement in Rail-Chairs, of which the following is a specification.

My invention relates to an improvemcntin the class of rail chairs known as headchairs, being the seats for the terminals of. rails, forming parts of switches in railroadtracks, and it is designed to afford an improved construction over a device belonging to this class and involving a bed-plate having welded transversely upon one of its surfaces a bar previously subjected to the action of dies to form the slots to admit the webs of the rails, and the chambers below the slots for receiving the rail bases or flanges, the forging operation also leaving a back to afford a stop to the ends of the rails.

The object of my present ii'lvention is to provide a head chair the construction of which shall be materially simpler than that of the chair llOl'QlllllGfOlB referred to, and which shall be cheaper to produce than the latter.

In the accompanying drawings, Figure 1 is a plan. view of my improved rail-chair, showing railsin position therein; and 2, a perspective view of the chair.

The manner of: procedure to construct my improved head-chair is as follows: I take a metal bed-plate, A, of suitabledimensions, and apply to it at suitable distances apart metal plates 1', one near each lateral edge, the plate. A and plates '1' having, if they are to be riveted together, previously been provided with rivet-holes to receive the rivets p, hereinafter described. The plates 0' are adjusted on the bed-plates in position to bring the rivet-holes in the former respectively coincident with those in the latter. Then a metal cross-bar, 15, preferably of the angular shape shown, and provided with parallel slots q, extending transversely and the desired distance apart from one edge of the bar B to near the opposite edge, leaving stops or backs 0 flush with the part .1, of the angle-bar, and thus of sufficient thickness to a tford the required strength, is imposed on the bars 1', restil'lg on the latter toward the opposite ends of its horizontal portion, while the vertical port ion .r rests on the bed-plate. The cross-bar may be likewise provided near its extremities with rivet-holes to coincide with those in the plates A and r, and through the coincident rivethol(-s in the parts, I r, and A, near each lateral edge of the bed -plate, areinserted rivet p, when the metal parts thus connected may be suit-ably heated and welded to combine them and the rivets "1'. This operation renders all the parts of the device practically integral, though the construction is readily recogn izable on fracturing the parts, which shows them to be individually distingu ishable alon the surfaces of their junction.

If it shall be desired to prop the cross-bar B between its extremities, (though this is not commonly necessary,) this may be accomplished byinsertingunderneath it on thebedplate a metal block, on, having rivet-holes to receive rivets p, passed into them through the plate B and extending through the l.) ed-plate.

It is not necessary that the parts of the chair thus formed shall, if riveted together, be also welded, as described, nor that if welded they shall be riveted, though I prefer to both rivet and weld them together. The gist of my improvement, however, consists in forming the chair of four separate pieces, A, r, r, and. B, and fastening them together by any suitable means.

Behind the cross-barB on the bcd-plate are stops Z to limit the play of the pivotal switchrail, (not shown,) which is thrown into align ment with the ends of the rails 7;, held at their flanges in the spaces between the parts rand m and at their web portions in the slots qand against the backs 0 thereof. It will thus readily be seen that my lllllJFOVHlllOlll? affords a construction involving in a material degree simplicity and cheapness over that referred to as being old and which is neither less eifective nor less durable than the latter.

\Yhat I claim as new, and desire to secure by Letters Patent, is-

1. A head-chair comprising, in combination, a bed-plate, A, a cross-bar, 13, having slots q, and plates 1', interposed between the crossbar toward its opposite ends and the bedplat-e, theIcross-bar, plates 0', and bed-plate being fastened together, substantially as described.

2. A head-chair comprising, in combination,

a bed-plate, A, an angular cross-bar, B, having slots q, and plates 0', interposed between the cross-bar toward its opposite ends and the bed-plate, the cross-bar and plates being fastened together and to the bed-plate, substantially as described.

3. A head-chair comprising, in combination, abed-plate,A, and an angular cross-bar, B,having slots q and riveted to the bed-plate through plates 7' toward opposite ends of the cross-bar, substantially as described.

4. A head-chair comprising, in combination, a bed-plate, A, a cross-bar, 15, having slots q, plates r, interposed between the cross-bar toward its opposite ends and the bed-plate, and rivets p, ext-ending through the parts B, r, and A, the said parts and rivets being welded together, substantially as described.

5. A head-chair comprising, in combination,

a bed-plate, A, an angular cross-bar, B, 11a"- ing slots q, plates 0, interposed between the horizontal portion of the cross-bar toward its opposite ends and the bed-p1ate, and rivets p, extending through the parts B, r, and A, the said parts and rivets being welded together, substantially as described.

(5. A head-chair comprising, in combination, abed-plate, A, a cross-bar, B, having slots q, plates 9", interposed between the cross-bar toward its opposite ends and the bed-plate, the cross-bar, platesr, and bed plate being fastened together, and a bar, m, secured underneath the crossbar-between the plates r,substantially as described.
